lock-smith

Automated security checks for one x402 endpoint — not a penetration test. Eight non-destructive, unpaid probes: paywall presence, challenge sanity, garbage and forged (invalid-signature) payment rejection, exposure surface, error hygiene, body-size cap, discovery consistency. Returns SECURE / FINDINGS / EXPOSED with a fix note per finding. Use this when you operate an x402 route and want its locks checked the way an attacker would rattle them.
